Description

An anti-aging cosmetic and an anti-aging cosmetic manufacturing method comprising a nanoparticle-containing solubilized soluble oleanolic acid

More specifically, the present invention relates to a cosmetic for improving skin wrinkles. More specifically, the present invention relates to a cosmetic preparation for improving skin wrinkles, which comprises solubilizing and micellizing oleanolic acid as an insoluble polymer, This invention relates to an anti-aging cosmetic comprising nanoparticles useful for increasing solubility and improving skin permeability.

Skin aging occurs through two main processes. The change that occurs with age without any special environmental factors is called intrinsic aging, and the change in appearance on the face, neck, and hands due to long exposure to environmental factors such as ultraviolet light It is called photo aging or extrinsic aging.

In addition, the main cause of the endogenous aging is the accumulation of damage to the constituents of the body due to reactive oxygen radicals produced in the metabolism of the body. On the other hand, extrinsic aging is different in that harmful free radicals are produced by ultraviolet rays. Once active oxygen is produced, failure to effectively remove by various protective devices in the body results in a series of inflammatory reactions leading to skin damage, and typical damage to the skin is wrinkled skin.

In order to improve the skin wrinkles, ascorbic acid,? -Tocopherol, retinol and derivatives thereof, superoxide dismutase (SOD) and the like are mixed with cosmetics as a substance for free radical scavenging function or skin wrinkle improvement, And other skin diseases. However, they have poor long-term stability and are hard to expect a substantial effect. For this reason, development of a material which is more safe and effective for improving the wrinkles of the skin has become an important task in the cosmetics industry, and many studies have been conducted.

In addition, retinol is widely known as a substance having a wrinkle-reducing effect in cosmetics, but it is vulnerable to heat or light, and it is photosensitive, so that a problem of making the skin more sensitive when exposed to sunlight is suggested.

In recent years, oleanolic acid has been proposed as an alternative to retinol. However, the oleanolic acid has poor solubility in a solvent such as water and solubilized in general cosmetics using water as a solvent There was a difficult problem,

However, when oleic acid is solubilized using oils, surfactants, and solubilizers as a general method, cosmetic products have problems of difficulty in permeation of the skin due to large sedimentation and particles.

The following are representative prior arts relating to cosmetic products having the function of improving skin wrinkles.

Korean Patent Registration No. 10-1802963 relates to a cosmetic composition using a fermented extract, which comprises a fermented extract of a medicinal substance containing red ginseng and ginseng; Sustained fermentation extract; And a soybean fermentation extract. According to the present invention, it is possible to constitute a composition containing natural medicinal materials, fat, soybean fermented extract as an active ingredient, and the cosmetic composition further comprises oleoanic acid as a skin pore filling agent.

In addition, the cosmetic composition according to the above-mentioned prior art can provide a skin-improving effect such as prevention of skin aging and alleviation of wrinkles by including a natural medicinal material, a fat and a fermented soybean extract as an active ingredient. However, There is a problem that the oleanolic acid used as a pore-shrinking agent of the skin is very insufficient in availability. Therefore, there is a need for continuous research and development for solving the problem.

<Anti-aging cosmetics containing nanoparticles useful in solubilization of poorly soluble oleanolic acid>

0.01 to 1 part by weight of oleanolic acid, 1 to 30 parts by weight of a solubilizer, 1 to 30 parts by weight of an amphiphilic polymer (Poloxamer) and 39 to 97.99 parts by weight of distilled water To an anti-aging cosmetic comprising nanoparticulate solubilizing solubilized oleanolic acid. At this time, it is preferable that the nanoparticle-containing material has a particle size of 20 to 150 nm in order to improve permeability to the skin.

Oleanolic acid is known as a substance having an antioxidative effect. In the present invention, it is a substance exhibiting an effect of improving skin wrinkles due to the constantly effective action.

Retinol, which is known as a skin wrinkle-reducing substance, has a disadvantage in that it is unstable to heat or light and its effectiveness is reduced by half when it is contained as an effective substance in cosmetics. However, when the oleanolic acid is used, Has been proposed as an alternative effective substance that can improve the disadvantages of retinol.

However, Oleanolic Acid is hardly soluble in water, which is a main component of cosmetics, and has a problem that it is difficult to permeate the skin because of its large particle size. On the contrary, the present invention provides a method of preparing a solution of an oleanolic acid by mixing a solution aid and an amphiphilic polymer in the oleanolic acid so as to be able to react favorably in a soluble micelle form, Anionic acid was dissolved in distilled water to make cosmetics.

In addition, the solubilizer serves as an adjuvant for both hydrophilic polymers which are dissolvers to micellize the oleoanic acid.

At this time, the dissolution aid may be any one or more of ethylene glycol, propylene glycol monocaprylate, tetraethylene glycol, polyethylene glycol, polypropylene glycol and polybutylene glycol, preferably ethylene glycol or propylene glycol And cocaprylate may be used.

The dissolution aid may be used in an amount of 1 to 30 parts by weight, preferably 2 to 10 parts by weight, based on 0.05 to 1 part by weight of the oleanolic acid. If the solubilizing agent is contained in an amount of less than 1 part by weight based on 1 part by weight of the oleanolic acid, the dispersion of the oleanolic acid is incomplete and the release of the oleoanic acid becomes difficult at the time of use of the cosmetic, When the amount is more than 30 parts by weight based on 1 part by weight, there is a problem that the stability of the oleanolic acid is insufficient and the reagent is wasted.

In order to further improve the solubility of the oleanolic acid by the solubilizing aid, it is possible to further use glycofurol, polysorbate, crmolpore, Solutol HS 15 and the like.

In addition, the amphiphilic polymer plays a role of micelle formation and preferably triblock copolymers in the form of <polyethylene oxide (PEO) -polypropylene oxide (PPO) -polyethylene oxide (PEO)> More preferably, at least one of Poloxamer 184, Poloxamer 185, Poloxamer 188, Poloxamer 124, Poloxamer 237, Poloxamer 338 or Poloxamer 407 can be used.

In connection with the above, the triblock copolymer is preferably contained in an amount of 1 to 30 parts by weight, more preferably 5 to 20 parts by weight, based on 0.01 to 1 part by weight of oleic acid. If the triblock copolymer is contained in an amount of less than 1 part by weight based on 0.01 to 1 part by weight of oleanolic acid, there is a problem that precipitation of oleanolic acid occurs, and when the amount of the triblock copolymer is 30 parts by weight per 1 part by weight of oleanolic acid There is a problem that the particle size is increased and the stability is lowered.

In addition, both of the above-mentioned biocompatible polymers have a high mixing ratio within the above-mentioned mixing ratio, so that the nanoparticle useful product is made into a gel-like form, and as the mixing ratio is lowered, the prepared nanoparticle-containing mule can be made into a liquid form.

Further, the distilled water serves as a solvent for dissolving the oleanolic acid, the dissolution aid, and the biodegradable polymer.

At this time, the distilled water is preferably contained in an amount of 39 to 97.99 parts by weight based on 0.01 to 1 part by weight of oleic acid.

If the distilled water contains less than 39 parts by weight of oleanolic acid based on 0.01 to 1 part by weight of the oleanolic acid, there is a problem that the oleanolic acid is not fully micellized. When 0.01 to 1 part by weight of oleanolic acid is used, There is a problem that the concentration of the produced nanoparticle useful substance may be excessively lowered.

In connection with the above, the oleanolic acid, the solubilizing aid, the amphiphilic polymer, and the distilled water may be mixed together to form the nanoparticle useful product, but preferably the oleanolic acid and the dissolution aid The oleanolic acid first mixture is added to the oleanolic acid first mixture and then the two ampholytic polymers are added to the oleanolic acid first mixture, and then the mixture is stirred under heating to prepare a second oleanolic acid mixture, The second mixture of ricinic acid may be mixed with the distilled water to make the nanoparticle useful product.

That is, the first oleanolic acid mixture is composed of an oleanolic acid and a solubilizing agent mixed with stirring, and the solubilizing agent is preferentially dispersed and mixed in oleic acid.

More specifically, when the dissolution aid is first dispersed in the oleanolic acid, the dissolution aid is first dissolved in the mixture of the oleanolic acid particles before the bilayer fibrillating polymer which mainly forms the micelle reacts with the oleinic acid, It is possible to obtain an effect of improving the micelle formation of oleanolic acid.

The oleanolic acid second mixture may be prepared by mixing the first oleanolic acid mixture with a biocompatible polymer. The oleanolic acid contained in the first mixture of oleanolic acid may be heated to improve the reaction activity And is a constitution for increasing the solubilization of oleanolic acid having poor solubility.

At this time, it is preferable that the heating temperature for making the oleanolic acid second mixture is maintained at 30 to 80 캜.

That is, if the heating temperature is less than 30 ° C, the reaction activity of oleanolic acid is somewhat insufficient, and if it exceeds 80 ° C, the oleanolic acid may be deteriorated.

The present invention relates to a method for producing an oleanolic acid, comprising: a first step of mixing 0.01 to 1 part by weight of oleanolic acid and 1 to 30 parts by weight of a solubilizing agent with stirring to prepare a first mixture of oleanolic acid; A second step of adding 1 to 30 parts by weight of an amphiphilic polymer to the oleanolic acid first mixture, followed by stirring and mixing under heating to prepare a second oleanolic acid mixture; A third step of adding 39 to 97.99 parts by weight of distilled water to the oleanolic acid second mixture, followed by stirring and mixing to form a nanoparticle useful product; And a fourth step of preparing a cosmetic product by mixing the nanoparticulate useful product with a carrier component contained in a known cosmetic product. The method for manufacturing an anti-aging cosmetic product comprising the nanoparticulate product obtained by solubilizing the poorly soluble oleoanic acid .

The method of manufacturing a cosmetic product according to the present invention can produce a cosmetic product containing a nanoparticle useful product having a particle size of 20 to 150 nm in which the whitening improving active substance is encapsulated.

That is, in the first step, 0.01 to 1 part by weight of oleanolic acid and 1 to 30 parts by weight of a solubilizing agent are mixed with stirring to prepare a first mixture of oleanolic acid, and dissolution of poorly soluble oleoanic acid And the auxiliary solubilizing agent is preferentially dispersed and mixed in the oleoanilic acid.

That is, the description of the both hydrophilic polymers will be replaced by the above description. However, the stirring mixture of the first oleanolic acid mixture and the biodegradable polymer is preferably carried out in a warmed state for the purpose of solubilizing the oleanolic acid, and the heating temperature is preferably maintained at 30 to 80 ° C.

In the third step, 39 to 97.99 parts by weight of distilled water is added to the oleanolic acid mixture (2) and stirred to prepare a nanoparticle useful product. The oleanolic acid solubilized in the second step is dissolved in a micelle- It is the process of making things.
